I am using iphone 4s and the battery looks good. The battery used during bedtime of 8 hours about 2 to 5 % at home usj.

However when i am at tebrau my battery drops 7% for 7 hour sleep. The sudden increase could be due signal problem? I also notice battery drop faster when surfing.

My current usage is 1.3 hour and standby is 9.5 hour and the battery drop from 100 to 76% .Anthing not right? Thanks.

Usually i just charge until 100% which takes about 2 hours. The battery usually drop 3-7% during my 8 hour sleep.

I just noticed the longer i charge the better. Last night i charged about 5 hours (2 hours full charge, next 3 hours extra after that cuz i forgot to remove it).

After 4 hours standby, the battery is still 100%.
Perhaps trickle charge is better to fully charge the battery?
